Tr) all whom it may concern Be it known that l Alrrmiiic W. Pm s vozulf, a citizen of the United Statwc, and a 1 dent of Binghmnton, in he county of Broomo and State of New York, have invented now' and useful Improvements in Registers, of which the following is: a spooification.

My invention is an improwmont iii-registors, and has for its object to provide a, form of supporting frame for the louver-s and a form of face plate or grill so arranged that tho commotion l'lGlZW'CCIi tho grill and the sun porting frame will ho cr.. nc; =alrad, and wlneroin, the operating mechanism for opening and closing the loiilvors is mounted u zon rollers for. mm'emont in a single: ho, and Whomin the said mechanism "1 non-tad to the .louvors in such maonor that tho pull on tho louvors will he approxin'latoly porpondicular to their planes.

' Fig: 5 1s a-partlal 'porapofiiw virw oi" mm of the. louvra r-il'mwin 5 a Fig 53 is a porn"; 3 n'mdiliod Form of F0 'llio pi'wont omhod mention is shown in tho o'pmii'ng 1 of a dlo'or 9 or tho like, and the improvement comprises a rochmgular frame rruisistiug of? aid. 1 lls 3 and and walls 4-.llm Hide and and, wallql ing: latoral outwardly i; their uppor odgrs, for engaging tho upnor surf-urn of H10 floor 2, to support tho frame within tho opening. Ono (it tho and walls t has an inwardly hunt flange at its lower odgo forming! a, trough or fraokway fi, For a purposo't'o ho l'ator lhFZCIlbF-(l. and the said walls have imvardly wt-ending oblique flanges 7 at thoir lowor odors,

'lho ond walls/l smpport tholouvoro or is adaptml to ror'oivu a stub shu ft or journal pin 10 oon-noctmlwith the adjacent and wall 4. At that. 'wall 4. having the trough 6, the shafts or,journal pins 10 engage openings in tho side walls of the trough, and. the up ponito wall 4; may have a flange for a like purpose.

' It will ho noticed from an inspection of Fig. that each louver is grooved 1ongitudinally at its center, and that the hearings 9 are in those grooves. At opposite sides of tho grooves the louver-s are curved sli htly as shown, to engage at their opposite si e edges in the manner shown in Fig. 3, to make a tight closure in the frame, when the said rz-ilvoa or louvers are closed.

The face plate. or grill 11, which is of cast maturial, has the usual openings for tho pass go of: air the said plate being of larger sum than tho frame and extending lm mn l tho :hamo at the opposite sides thorcmf to lap upon the. floor as shown. The ooh- 1" r-dgo of the time plate is ribbed on its under surface as shown at 12, for 'enga 'ng the. floor, and adjacent to each side 3 o the frame, the face plate has an inwardly and downwardly oxtuudi-ng oblique, flange 13. Each of the sides: 3 is; provided at the flange 5 with an inwardly hunt angular portion 14, tho upper wall of tho said portion being shapod to lap upon tho under face of the adjacent flang'o l3, and scro'W bolts 15 are passed through oprnings in the flange and through slots 16 in the said upper wall of. tho'iuwardlv bout portion to connect the t'a'mws with the. face plate.

'lho ln' li'z; 153 area noar the (ends; of the sides and the lmwr wall of tho hiwardly bent portion orcwidi s a lock for holding the not from linrnin while, the connection is being mado, and :wcoss' is m'mittrd to the screw bolts; tln m'zgqh tho openings of: tho faoo la te.

l lauh lmwvr is provided near one on and "(war one shin-edge with a hearing 17,, and oach of (slime ooarln s is ndap'tod for engagement by ono of t in arms 18 ofa. crank. The othor arm 19 of (each crank shaft engages a slide or carriage 30 mounted to move on rollers 21, ruun'ingin tho trough shamed guidoway, the said rollers having concave or grooved peripheries for engagement by the slide or carriage.

The said slide. is formed by bending the side edges 22 and 23 of a plate, laterally, the lower edge 22 being of angular form, form ing an angular rib for engaging the roller, while the uf'pper ed 0 is oblique, and th froo edges or the sa-i edges move in contact with. tho inner fame of the adjacent side wall 4. Astop 24 extends inwardly from the no I said side wall 4, engaging the upper surface of the ed 23, to prevent upward movemcnt of the s ide or carriage, and to hold it in contact with the roller.

The carriage is moved by means of a foot plate 25, which extends upwardly through a slot 26 in the face plate 11. The said slot is rovided at each end with indications, the otters O and S in the resent instance, indicating that when the cot plate is adj aoent to the letter O the louvers will be open, while when the foot plate is adjacent to the letter S the louvers will be closed. It will be evident that when the foot late 24 whose upper face is roughened in t e usual manner, is pushed longitudinally of the register, the carriage moves upon the rollers 21 without friction, and the pull upon the louvers by the crank shafts 18-19 is nearly perpendicular to the planes of the louvers so that friction is reduced to a minimum.

The arrangement of the flanges 13 and the inwardly bent portions 14 ermits the con nection of the face plate with. the frame to be concealed, and it is not necessary to provide openings in the edge of the face plate for receiving bolts or screws to connect the face plate. If desired, the screw bolts 15 may be dispensed with and their place taken by ordinary wood screws which will engage the floor or joists. The face plate, it will be noticed, has its edges rounded and brought to a sharp edge at the floor line. The foot plate has no lateral movement with respect to the plane of the face plate, that is when the register is horizontal, the movem nt of the foot plate is altogether horizontal, while when the register is vertical, the movement of the foot plate will be altogether vertical.

The crank arms 18 are journaled in the bearings 17 to move freely therein, and the entire weight of the operating device and any pressure exerted on same, is supported by the wheels or rollers.

In. Figs. 6 and 7 is shown a modified form of foot plate. In this construction the carriage 22 and 23" is similar to the carria e 22---23, and the foot plate 30 has opposite y extending lugs or branches 31 at its lower end. Inclined shoulders 32 are formed between the branches andthc body of the plate at their junction, the said shoulders being at opposite sides of the foot plate. The ends of the branches are beveled to fit smoothly within the-edge 22 of the carriage, and lugs 33 struck up from the edge 23 of the carriage are bent over uporr the shoulders to prevent upward movement of the plate. Tl ce foot plate is thus held to the carriage wi hout rivets, screws or the like.
